我無法弄清楚如何在php-fpm中禁止通知級別的日誌事件，如下所示：PHP-FPM如何抑制通知日誌級別並仍然捕獲警告日誌/etc/php-fpm.conf
[07-Feb-2015 10:06:48] NOTICE: [pool www] child 19591 exited with code 0 after 52040.698062 seconds from start
[07-Feb-2015 10:06:49] NOTICE: [pool www] child 17234 started
[07-Feb-2015 10:06:50] NOTICE: [pool www] child 19822 exited with code 0 after 52014.845635 seconds from start
[07-Feb-2015 10:06:50] NOTICE: [pool www] child 17261 started
[07-Feb-2015 10:07:33] NOTICE: [pool www] child 17784 exited with code 0 after 52246.014015 seconds from start
雖然仍然捕獲類型警告的日誌事件，例如將由php中的error_log（）函數創建。記錄事件如以下：
[07-Feb-2015 11:46:44] WARNING: [pool www] child 32465 said into stderr: "NOTICE: PHP message: Array"
[07-Feb-2015 11:46:44] WARNING: [pool www] child 32465 said into stderr: "("
[07-Feb-2015 11:46:44] WARNING: [pool www] child 32465 said into stderr: " [6] => 363"
[07-Feb-2015 11:46:44] WARNING: [pool www] child 32465 said into stderr: ")"
[07-Feb-2015 11:46:44] WARNING: [pool www] child 32465 said into stderr: ""
從php.net它指出可變LOG_LEVEL accecpts以下字符串類型來調整記錄的捕獲的水平：
錯誤日誌級別。可能的值：警報，錯誤，警告，注意，調試。默認值：通知。
http://php.net/manual/en/install.fpm.configuration.php
於是，自然而然地在我的/etc/php-fpm.conf文件我設置的配置值： LOG_LEVEL：預警和服務重新啓動。然後我得到上述的無日誌事件。
我找不到任何文檔指出每個log_level選項所做的事情，而且似乎除了通知之外的任何東西都會壓制所有內容。
這是在centOS機器上使用php-fpm 5.4或5.5。
